Assessment of Hypnosis Knowledge Among Dentists: A Cross-Sectional Study

ABSTRACT Objective: To assess the attitudes, experiences, training levels, and interest in future education regarding the use of hypnosis by dentists working in Dental Clinic of Monastir, Tunisia. Material and Methods: A cross-sectional study was conducted among 330 dentists working in Dental Clinic of Monastir in November 2019. Students, internship, residents, and professors were randomly selected. This was a survey with a structured questionnaire mailed to all dentists. The questionnaire was pre-fabricated, simple, and close-ended. Data were analyzed using SPSS 24.0 statistical software. Results: A total of 202 dentists respond to this survey. 54% of the participants were interns with a female predominance (66.5%). Findings revealed that beliefs toward hypnosis in the sample were generally positive. Using a visual analogue scale, dentists reported having moderate acknowledge in hypnosis (3.4). 60% of the participants in our study consider that hypnosis is useful in dentistry and, more particularly, in pediatric dentistry. 78.2% of respondents want to follow training courses in hypnosis. Conclusion: Our survey highlights the weak knowledge of participants in hypnosis and reveals certain misconceptions about this procedure. More efforts are required to better educate dentists about hypnosis's benefits in their practice.

Prevalence of Molar Incisor Hypomineralisation Among School Children aged 7-12 years in Tunis, Tunisia

Abstract Objective: To evaluate the prevalence and the characteristics of Molar Incisor Hypomineralisation (MIH) in 7-12-year-old children in Tunis, Tunisia. Material and Methods: This study was designed as a cross-sectional study, in which school children aged 7 to 12 years were included. A total of 510 children (257 girls and 253 boys) who had their first permanent molar and incisors were evaluated using the 2003 European Academy of Paediatric Dentistry (EAPD) recommendation criteria were examined. Descriptive data analysis and Pearson's chi-squared test were performed (p<0.05). Results: A total of 510 children were included in the study. MIH was present in 35.4 % of our study population. Boys exhibited slightly higher MIH (19,4%) and Post Eruptive Breakdown (PEB) (7,3%) prevalence compared to girls, but the difference was not statistically significant (p=0.07). Moreover, demarcated opacities were more prevalent than PEB. More precisely, the main prevalence without PEB was MIH with white/creamy demarcated opacities, which was more frequent than yellow/brown demarcated opacities (p<0.05). Conclusion: The prevalence of MIH in Tunis was 35.4%, with no difference between girls and boys. The main MIH type prevalence was white/creamy demarcated opacities without PEB.
